(EMI\/EMC) in switching power supplies, data lines, and power circuits.<\/p>\n<h4>\ud83d\udd27 Technical specifications<\/h4>\n<ul>\n<li>Core: 5026 toroidal ferrite (13 mm outer diameter, 6 mm inner diameter, 5 mm thick)<\/li>\n<li>Wire: 0.45 mm diameter enamelled copper<\/li>\n<li>Available inductance values: 10 \u00b5H, 22 \u00b5H, 33 \u00b5H, 47 \u00b5H, 68 \u00b5H, 100 \u00b5H, 220 \u00b5H, 330 \u00b5H, 470 \u00b5H<\/li>\n<li>Recommended maximum current: 3 A<\/li>\n<li>DC resistance: typically 0.6 \u03a9 to 1.5 \u03a9 depending on value (measure each inductor)<\/li>\n<li>Useful frequency range: from a few kHz to several MHz<\/li>\n<li>High impedance at HF for effective noise filtering<\/li>\n<\/ul>\n<h4>\ud83d\udca1 Typical applications<\/h4>\n<ul>\n<li>EMI\/EMC filtering in switching power supplies and DC-DC converters<\/li>\n<li>Noise suppression on USB, CAN, Ethernet, I\u00b2C, and SPI lines<\/li>\n<li>Output-voltage smoothing in regulated power supplies<\/li>\n<li>Protecting audio and RF circuits from interference<\/li>\n<li>High-frequency resonant and decoupling circuits<\/li>\n<\/ul>\n<h4>\ud83d\udee0\ufe0f Pinout and connections<\/h4>\n<ul>\n<li><strong>Axial leads:<\/strong> solder both enamelled-copper wire ends directly to the PCB or fit them into 2.54 mm through-hole supports.<\/li>\n<li><strong>Placement:<\/strong> position the core near the input or output section of the converter for effective noise filtering.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Low-leakage toroidal ferrite inductor for filtering noise and suppressing
